Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The high pressure A/C hose vibrated and caused a hole. The car is only 3,000 miles over warranty. The dealership indciated that it went out because it was not installed properly. Despite the fact that they caused the problem the insist that I pay for the repair. They said it won't go out again because they will install it properly. They wanted $370.00 to repair it. I can't afford the cost at the moment so I just picked up from the dealership today.”

NHTSA complaint #10070501, filed 2004-01, 39,000 miles

“I've just recently had to put $900.00 into a head gasket replacement on a 1999 Plymouth NEON. The dealer agent had stated that it is an ongoing issue that has been reported to chrysler and unless the vehicle is covered under a service contract, chrysler is doing absolutely nothing about it for the consumer. The dealer has replaced head gaskets on neons at 30,000 miles and higher. With as many vehicles I've owned in my life, I've never had to replace a head gasket. Even at 200,000 miles.”

NHTSA complaint #10030413, filed 2003-07, 90,000 miles

“My NEON has 86,000. I have had it from new. In november of 2003, I had my second head gasket replaced. I believe I am on my way to the 3rd. I have an appt with the dealer tomorrow. I have had the EGR valve replaced and my sunroof has not worked for the last 4. I had it fixed 4 years ago only to have it malfunction within 4 months. The dealer stated it was not under my warranty, even though I have the extended warranty. The last dealer admitted there was a problem with the head gasket from factory and chrysler changed them. …”

NHTSA complaint #10110002, filed 2005-02, 86 miles

“Head gasket leaking on driver side of car. My mechanic told me the repair would cost over $800.00, and stated that a recall was made by Plymouth on my Plymouth NEON. He suggested I contact the dealership. I contacted the service department of jack powell chrysler Plymouth dodge, escondido, ca where I purchased the car new in sept 1999, and told them about my head gasket oil leak. They asked me for my VIN number. I waited 15 minutes for a woman to return to the phone and said there was no recalls for my vehicle, then hung up on me when I started to ask a question. …”

NHTSA complaint #10018398, filed 2003-05, 73,197 miles

“I took my car in for a 60,000 mile check-up and was astounded to learn that the head gasket was leaking at only 57,000. I could not afford the repair at this time and the mechanic said that nothing was leaking that would hurt the engine, but it should be taken care of soon. In all the years I've had a car I've never had a leaking head gasket and at 57,000, too. My last car, also a Plymouth, had over 127,000 miles on it and I never had problems with the engine. I do not misuse my vehicle, I have the oil changed every 3 to 6,000 miles and do everything possible to keep it trouble free.”
